Adding pointers to RPG language. Was more based() %addr array questions!!! found my problem:

Hans, I don't think "adding pointers to the language was a bad idea."

You should be taking credit, not blame, for adding them.

Many things that would be difficult or impossible to do without pointers are 
relatively easy to do with them.  For example: dynamically allocated storage, 
using many system APIs and C functions, navigating complex structures, handling 
blocks of data larger than 32767 bytes, etc.

rpg400-l messages indicate that many RPG IV programmers are using them to great 
advantage.
